To all whom it may concern? o Be it known that I; JOHN SoHnDLE ,.acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvaniai have invented .certain -newand'useful-Improvements in Bottle Stoppers, of aspecification. V- 7 Oneobject off'my, invention is to provide an improved stopper which-willmorecom pletely seal-"the necks of bottles or other containers thanstoppers 'made prior to my present invention. I

which the following is myimproved stopper of such construction thatit"can be cheaply and quickly manu' factured andyso thatit can beeasilyand quickly attached toor removed from a;

bottle. r a i 3 These objects, and other. advantageous ends which willbe: described hereinafter, I attain in the following manner, referencebeing had to the accompanyingd i inwhich- 2 Figure 1 is .a top planview'showing my improved stopper applied to a bottle. 1 i Figure 2fis afragmentary section taken on the line 22 of Figure 1, o Figure 3' is asection taken" on the line of Figurei2,

View ;of' the same general cha'racteras shown in Figure3, illustrating the parts before they are moved into their clampingpositions, and i o Figure 5 is'a developed'view showing a blank'whichcan be stamped out-of sheet .metal andhafterward s bentto, formthe clamping lever illustrated inyFigures 1 to t-inclusive.

the Ineckof a bottle. My improved stopper includes a soft rubber nippleThaving a cylindrical sleeve 8 adapted to be'projected i into thethroat90f the bottle neck 6. The

flange 10' will be compressed firmly against make Referring to thedrawings, represents seal:

This link has an'upper yoked end 15- in the form'zofa loop anda-slovvefr hooked end 16.

One side 17 of the link is continuous {and joins .the yoked end 15 withthehooked" end 16'.) Theotherside-lB oftheylink is 'sep .arated toprovide a'space' lgfbetw'eenrth'e up itur'nedfend' 2O of the hookedportion 16'. and V V vthe lower 'end of thei side. l8,r asx-'clea rlylugs21 projecting inwardly atsdiffe'rent lev- 1 els for a purposehereinafter describedif I 'A tapered spreading plug 22, 'which is apreferably: made frusto-conical Y. and of a p 23 adapted-to -beihookedover the 'u'pturned I shown in Figures 3 andML The side lZfihas hard:substance such asHmetaLhasan eyelet end420 so asto'ihangin thehooked-portion lfi'of the link; This'plug 22l1asitsfupper-- most portionof 7 smaller diameter :thanrthe '80 larger portion atthegbottom ofgreat-(indi I internal diameter offlthe. sleeve '8 andflits am'eter;than theinternal, diameter .of the Sleeve 8 sothzttfby pullingupward-on: the

I v. provide a lever 24 whichlis pref-e :made of sheet metal firststamped in'the bent-into the shape illustratedin- Figure s 1 to 4inclusive. This lever haswa central .link '14: relatively to'the sleeve8, the plug handle portion 25 and -two wingsi26. 'VThese' wings arejbent substantially. v parallel I to.

'95 each other and includecurvedcamiedges 27 which terminate infingerss-28. irt' each side of a cutoutvportion or-recess .29.;.';Tl1is recess 29is arranged in linew-ith the-handle 25. and the fingers 28arefoldedtoWard each other so that their outer: edges 30 abut each otheras shown'in Figures l and;2.

The wings 26',- when the d'evicegis in itsassembled position, arelocated adgacent iop-k posite faces of the link 14 so Z'thatthexfi'ngers 28 extend'througlrthevoked top 15 of j the link'with theside 17 ofthe, link extending through the. hole provided by the out out portion 29of the lever24lil. V .The cam edges 27 are made' convex from i asconcave as shown in Figure 2.

they can be made to engage the under surfaces ofthe lugs 21 f a greaterspreading" action is desired or if the nipple 7 is made shorter -than:that-; illustrated; In; other W'ords, the: device is vmadetoaccommodate condit ons 'offvarlo-us 'foliarac'tersa so that the stoppercan be' niade to seal container throats of. different characters, '5

iVlie'n' the stopper is tdbe attaoliechfthe,

' parts :are arranged infthe "positionsshoivn in vln igure 4;, thesleeve being positioned Within the throat'of the bottle vith the flange10; in abutinent'with' the toPsurfac'e llqthcreoiii- In this positionthe plug 22i's -below'the nippie 'and the camedges 27' .en-

gage the top surface of the disk; To "seal thethroat of the bottle thelever2f is moved so that the cam edges 27 will rocli' on the np persnrfaceioiii the "disk and th e fingers28 .Willpull'the link'upWardlyi-nntil the-plug 22' partway enters the lowerend o'f the sleeve8"and 'compresses said sleeve into firm sealing engagement with theinner surface of the throat 9; the fingers 28 moving upwardly sintilthe" points-131 engage the dislrl2gafter which a'con'tinued downward I-niovement of :the handle. 25 awnicanse' 'the V V 5 .5 edge 32 toengagecthe dislras shown in Fig- 'u're 3 and the points 31 to move intoposition at the opposite Sid'eofavertical plane passing downwardlythrough" the fingers 28, I ln'other Words 'the points-.31:are moved.to-a' position off cente'nan'd it is impossible for any expanding actionof-the' ruhherof the nipple to accidentally swing 'the' handle Iupwardly afterit once reaches theposition shown inFigure-3; IThus-theparts oifthe ,nipple are held in firm'slidin'gengagement .wvith theinner surfacefof the throat ofthe bottle and also; againstthe topsurface .11 of the bottle neck; 5 V i The" link, if desired, can bestanipediout of. metal and it is obvious that the parts can he readilyassembled or disassembled. For

' :examplethe'plng'22",vwhen the nipple is out of the neck ofthe-bottle;- can be readily detached from the hooked portion 16 byslightly-expanding the lower end of the nipple and throwing the eyelet23 over the upturned :end 20 of the hooked portion.

o'After the plughas been detached the link can bep ulled ont' of thenipple and disk, and after, this action the lever can be pulled downalong the side 18 ofithe'link by first --throwingithe link overtheIhookedv-end15 and When 'the fingers 28 reach the-space19 Y i it willreadily become-detached from the 1 link. Itiis thus an easymatter toreplace Letters Patent is any of the parts such for example if, it isdesired to substitute a new rubber nipple fVVhile I have. describednay-invention as taking a particular form, it will be understood thatthevarious parts of my inven- 7 tion' may be changed 1' Without departingfrom the spirit thereof, and hence I'do not limit myself to the preciseconstruction set ,forth, but consider that I am at liberty to make suchchanges and alterations as fairly come Within the scope of the{appendedclaims.
